TSX564AIPT Equivalent & Substitute Parts

Part Overview

The TSX564AIPT is a CMOS amplifier integrated circuit manufactured by STMicroelectronics, containing four independent rail-to-rail operational amplifier circuits in a 14-TSSOP surface mount package. This device is classified as an active product with automotive-grade qualification under AEC-Q100 standards. The TSX564AIPT is designed for applications requiring low-power, rail-to-rail amplification across extended supply voltage ranges from 3V to 16V.

Substitute parts are identified when equivalent functional performance can be achieved within the constraints of the allowed electrical and mechanical parameters specific to the linear amplifier category. Substitutes must maintain compatibility with the 14-TSSOP package format, support the same supply voltage range, and deliver comparable output characteristics for direct circuit replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSX564AIPT are qualified based on the following criteria:

Package Compatibility: All substitute parts must use the 14-TSSOP surface mount package with identical 0.173" (4.40mm) width dimensions to ensure direct PCB footprint compatibility.

Circuit Configuration: Substitute parts must contain four independent amplifier circuits to match the quad-channel architecture of the main part.

Output Architecture: All substitutes must feature rail-to-rail output capability to maintain signal swing performance across the full supply voltage range.

Supply Voltage Range: Substitute parts must support a minimum supply voltage of 3V and a maximum supply voltage of 16V, ensuring operation across the same power supply envelope as the TSX564AIPT.

Operating Temperature Range: Substitute parts must operate across the -40°C to 125°C temperature range to maintain thermal compatibility in automotive and industrial applications.

Electrical Characteristics: Substitute parts must deliver comparable slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel within the constraints of the allowed parameter set.

Compliance and Status: All substitute parts must maintain active product status, RoHS3 compliance, and equivalent regulatory classification to ensure long-term availability and environmental compliance.

The MCP6H04-E/ST and MCP6H04T-E/ST from Microchip Technology meet all substitution criteria and are classified as general-purpose amplifiers with rail-to-rail output in the 14-TSSOP package.

Parameter Comparison

Engineering Selection Recommendations

TSX564AIPT (Main Part): The TSX564AIPT maintains active product status with automotive-grade qualification under AEC-Q100 standards. This device is suitable for applications requiring CMOS amplifier technology with higher slew rate performance (1.1V/µs) and greater output current capability (92mA per channel). The TSX564AIPT is available in Tape & Reel packaging with 15,709 units in stock.

MCP6H04T-E/ST (Preferred Substitute): The MCP6H04T-E/ST is a general-purpose amplifier from Microchip Technology supplied in Tape & Reel packaging, matching the packaging format of the main part. This substitute maintains active product status, RoHS3 compliance, and REACH unaffected classification. The MCP6H04T-E/ST delivers higher gain bandwidth product (1.2MHz versus 900kHz) and lower supply current consumption (135µA total versus 250µA). The device is available with 3,800 units in stock. The minimum supply voltage specification of 3.5V represents a 0.5V offset from the TSX564AIPT minimum of 3V.

MCP6H04-E/ST (Alternative Substitute): The MCP6H04-E/ST is functionally identical to the MCP6H04T-E/ST but supplied in Tube packaging rather than Tape & Reel. This substitute maintains all compliance certifications and electrical characteristics. The device is available with 2,918 units in stock. Selection of this variant depends on packaging and handling requirements specific to the application environment.

Both Microchip substitutes are suitable for direct replacement in applications where the 0.5V minimum supply voltage offset and reduced output current per channel (50mA versus 92mA) are compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the MCP6H04-E/ST and MCP6H04T-E/ST be used interchangeably with the TSX564AIPT?

A: The MCP6H04-E/ST and MCP6H04T-E/ST are electrically identical general-purpose amplifiers. The primary difference is packaging format: MCP6H04T-E/ST is supplied in Tape & Reel, while MCP6H04-E/ST is supplied in Tube. Both devices are compatible with the TSX564AIPT footprint and pin configuration. Selection between these two variants depends on assembly and handling requirements rather than electrical performance.

Q: What is the significance of the minimum supply voltage difference between the TSX564AIPT (3V) and the MCP6H04 variants (3.5V)?

A: The TSX564AIPT supports operation at 3V minimum supply voltage, while the MCP6H04-E/ST and MCP6H04T-E/ST require a minimum of 3.5V. Applications operating at supply voltages between 3V and 3.5V cannot use the Microchip substitutes. For applications operating at 3.5V or higher, this difference is not a limiting factor.

Q: How do the slew rate and gain bandwidth product differences affect substitution?

A: The TSX564AIPT delivers a slew rate of 1.1V/µs and gain bandwidth product of 900kHz. The MCP6H04 variants deliver a slew rate of 0.8V/µs and gain bandwidth product of 1.2MHz. The TSX564AIPT has faster slew rate performance, while the MCP6H04 variants have higher bandwidth. Applications requiring maximum slew rate performance should retain the TSX564AIPT. Applications prioritizing bandwidth performance may benefit from the MCP6H04 variants.

Q: What is the impact of the output current per channel difference?

A: The TSX564AIPT delivers 92mA output current per channel, while the MCP6H04 variants deliver 50mA per channel. Applications requiring output currents exceeding 50mA per channel must use the TSX564AIPT. Applications operating within the 50mA per channel limit can use either device.

Q: Are all three devices suitable for automotive applications?

A: The TSX564AIPT carries automotive-grade qualification under AEC-Q100 standards. The MCP6H04-E/ST and MCP6H04T-E/ST are classified as general-purpose amplifiers without explicit automotive qualification. Applications requiring automotive-grade components should retain the TSX564AIPT. General industrial and commercial applications can use the Microchip substitutes.

Q: Do all devices maintain the same package footprint?

A: All three devices use the 14-TSSOP package with identical 0.173" (4.40mm) width dimensions. PCB footprint compatibility is maintained across all three parts. No layout modifications are required for substitution.

Q: What is the supply current consumption difference between the main part and substitutes?

A: The TSX564AIPT draws 250µA total supply current. The MCP6H04 variants draw 135µA total supply current across all four channels. Applications with strict power consumption budgets benefit from the lower current draw of the Microchip substitutes, representing a 46% reduction in supply current.

Q: Are all devices RoHS3 compliant?

A: All three devices are RoHS3 compliant and REACH unaffected. Environmental compliance is maintained across all substitution options.
